1. Water Cycle 1.Evaporation 2.Condensation 3.Precipitation 1.Liquid → Gas Liquid water changes into water vapor, which is gas. 2.Gas → Liquid Water vapor cools and changes from a gas to a liquid. Clouds form by this process. 3.Occurs when rain, snow, sleet, or hail falls from the clouds onto Earth’s surface. R15

3. Water Cycle (cont.) 4.Infiltration 5.Runoff 4.The process by which water on the ground surface enters the soil. 5.Water, usually from precipitation, that flows across land and collects in rivers, streams, and eventually the ocean.

5. Water Cycle (cont.) 6.Transpiration (Perspiration →Plant Sweat) 7.Ground Water 6."Process by which water that is absorbed by plants, usually through roots, is evaporated into the atmosphere from the plant surface, such as leaf pores." - U.S. Geological Survey, 2011 (a) 7.Water that comes from the ground. It comes from precipitation that soaks into the ground.
